Congratulations on your first game! It's SUCH a big accomplishment, especially in a jam with limited time. Overall you did a good job implementing this game, but there are some things that could have been better: The character just going off the edge of the screen is a big one (especially if there's a ledge and it looks like they're just falling into a pit). The colliders also seemed very large compared to the size of the sprites, which made it difficult to judge how to make jumps and things.

Very nice graphics! Would be good if there were sounds as well. Obviously you need to sort out where the player starts in each screen (they should start on the screen). Personally I would prefer less text
